docker安装nacos集群
服务器说明：
1、单台服务器做nacos集群
2、nacos版本：2.0.0-bugfix
3、nacos外连其他服务器的mysql， 所以这里没写mysql安装配置
4、使用nginx转发
5、Docker version 19.03.13
6、mysql version 5.7
7、记得把下面用到的端口都放开
步骤：
- 新建操作目录
# 创建新目录
mkdir -p /usr/local/work/docker_compose/nacos-cluster
# 创建环境配置
mkdir env
# 写入配置
vim nacos.env
- 在nacos.env中写入下列内容：
# 加入其他配置，参考后面列出的可用环境变量配置
PREFER_HOST_MODE=hostname
NACOS_SERVERS=nacos1:8848 nacos2:8848 nacos3:8848
MYSQL_SERVICE_HOST=数据库地址
MYSQL_SERVICE_DB_NAME=数据库名称
MYSQL_SERVICE_PORT=数据库端口
MYSQL_SERVICE_USER=数据库用户名
MYSQL_SERVICE_PASSWORD=数据库密码
- 创建docker-compose文件
cd /usr/local/work/docker_compose/nacos-cluster
# 创建docker-compose.yml文件
vim docker-compose.yml- docker-compose.yml文件配置
version: "3"
services:
nacos1:
hostname: nacos1
container_name: nacos1
image: nacos/nacos-server:2.0.0-bugfix
volumes:
- ./cluster-logs/nacos1:/home/nacos/logs
- ./nacos1/init.d:/home/nacos/init.d
ports:
- "8848:8848"
- "9848:9848"
- "9555:9555"
env_file:
- ./env/nacos.env
nacos2:
hostname: nacos2
image: nacos/nacos-server:2.0.0-bugfix
container_name: nacos2
volumes:
- ./cluster-logs/nacos2:/home/nacos/logs
- ./nacos2/init.d:/home/nacos/init.d
ports:
- "8849:8848"
- "9849:9848"
env_file:
- ./env/nacos.env
nacos3:
hostname: nacos3
image: nacos/nacos-server:2.0.0-bugfix
container_name: nacos3
volumes:
- ./cluster-logs/nacos3:/home/nacos/logs
- ./nacos3/init.d:/home/nacos/init.d
ports:
- "8850:8848"
- "9850:9848"
env_file:
- ./env/nacos.env- 启动集群：
# 在nacos-cluster 目录下执行命令
docker-compose up -d
# -d 代表后台运行- 验证启动：
http://服务器地址:8848/nacos
http://服务器地址:8849/nacos
http://服务器地址:8850/nacos
正常登陆就Ok
- 关闭集群：
docker-compose down- 配置nginx
upstream cluster{
server 服务器地址:8848;
server 服务器地址:8849;
server 服务器地址:8850;
}
server {
listen 8080;
server_name localhost;
location /nacos {
proxy_pass http://cluster;
}
}
访问：http://服务器地址:8080/nacos

遇到的坑：
宿主机安装了mysql 服务， 内网 所以其他人都可以连接， 然后上面nacos配置mysql地址的时候， 就直接用的宿主机地址，但是始终报错,如下

原因：记得把宿主机3306端口放开 放开 放开 ，docker容器访问宿主机的Mysql 相当于外网访问，
这个问题搞了一下午。。。。
